MissBeyoncé's bob

… it was like the Men in Black memory eraser came out and the crop never happened. In its place was a slightly crooked blonde half-bob, that Beyoncé sported when out for a stroll with Blue Ivy. Complete with flower-power headband and reflective aviators, this is a look that spells indecision. She has since had another style – shoulder-length waves – the cut that women get when they chicken out of short-short and still want to be able to do a ponytail. As such, it's deeply unsatisfying when worn by such a perfectionist as Beyoncé "I have notes" Knowles.

MissMIC moccasins

The posh-boy look went rampant in summer 2013 – with the MIC effect doing its worst to the British male. Moccasins and deck shoes were big offenders – unless you are Spencer Matthews flying to St Tropez for the afternoon on a whim, they should be avoided. The full outfit includes red trousers, floppy fringe and polo shirts. The polo shirt has also become the holiday signifier for one David Cameron but, as a grandson of a baronet, that's entirely fitting. The PM also seems to have swapped moccasins for dad sandals, but the less said about that the better.

HitKeira and James

When Keira Knightley and James Righton got married in early May, it was a low-key do in the south of France, with a pretty tulle Chanel dress and flats for the bride. The couple have continued to provide blessed relief from celebrities whose wedding celebrations appear to be synched to 24-hour news cycles (see Tamara Ecclestone). On honeymoon, Knightley wore dungarees, for God's sake. She's since been spotted in a series of cute flippy dresses and flats. Righton, meanwhile, is a man of plain T-shirts and Ray-Bans. Together, they are this summer's alternative Posh and Becks.

HitMidriffs

Having threatened for a couple of summers, a toned midriff became the red-carpet bodypart to flash this summer. If it sounds scary, it usually looked quite chic. Lily Collins, Jennifer Lawrence and Diane Kruger are fans of the look – but you have to do it in the right way. Belly buttons are a no-no – no matter how many crunches you do, it looks far too All Saints circa 1997. The exception to this rule is Rihanna, but she gets away with what is sure to become one of summer 2013's classic outfits: a crystal bikini and headdress at the Barbados carnival.

If Get Lucky was summer 2013's song, Instagram-style prints were the style hit that went platinum. You know the ones – a blurry sunset, a road with palm trees, cocktails, a Californian beach, a Miami view … the exact opposite of a rainy British bank holiday weekend. The tropical look will always look great. Who can resist a palm tree? Certainly not Disney star Bella Thorne. Like Get Lucky, though, it has been overplayed. Time to come back down to earth. For autumn, you'll want a print inspired by the classical world on your T-shirt. Your reference? The cover of Jay Z's Magna Carta Holy Grail.
